[texhax] Preserve space at end of expression enclosed in braces

[Uwe Lueck]

And does the \relax produce the wanted leading space? -- As usual, please back your request with an actual application of your macros that seems not to work properly. I expect that it is essential to have some non-blue text within the document environment. -- BTW, I consider \textcolor{blue}{...} safer than {color{blue}#1}, since I observed that vertical alignment with \marginpar{\color{blue}...} is wrong, while \marginpar{\textcolor{blue}{...}} is fine. This may interrelate with the request, I don't know. -- Uwe.
